Scientists trap light in a layer 1,000x thinner than hair

Researchers from the Faculty of Physics at the University of Warsaw, working with teams from the Łódź University of Technology, the Warsaw University of Technology, and the Polish Academy of Sciences, have created a structure capable of trapping infrared light in a layer just 40 nanometers thick. Their approach relies on a design known as a subwavelength grating made from a specialized material called molybdenum diselenide (MoSe₂). The findings were reported in the journ...
